In some individuals, the left renal vein passes posterior to the abdominal aorta instead of in anterior to it; [1] this is termed a retro-aortic left renal vein (also known as "The Vein of Schnitker"). If there is both a vein passing in front of and one behind the aorta this is called a circumaortic renal vein.
The interlobar veins are veins of the renal circulation which drain the renal lobes. [citation needed] They collect blood from the arcuate veins. The interlobar veins unite to form a renal vein. [1] Each interlobar vein passes along the edge of the renal pyramids. [2]
After filtration occurs, the blood moves through a small network of venules that converge into interlobular veins. As with the arteriole distribution, the veins follow the same pattern: the interlobular provide blood to the arcuate veins then back to the interlobar veins, which come to form the renal vein exiting the kidney for transfusion for ...
The human urinary system, also known as the urinary tract or renal system, consists of the kidneys, ureters, bladder, and the urethra. The purpose of the urinary system is to eliminate waste from the body, regulate blood volume and blood pressure, control levels of electrolytes and metabolites , and regulate blood pH .

This becomes the ureter. At the hilum, the ureter and renal vein exit the kidney and the renal artery enters. Hilar fat and lymphatic tissue with lymph nodes surround these structures. The hilar fat is contiguous with a fat-filled cavity called the renal sinus. The renal sinus collectively contains the renal pelvis and calyces and separates ...
Oxygen-poor blood enters the right side of the heart through two large veins. Oxygen-rich blood from the lungs enters through the pulmonary veins on the left side of the heart into the aorta and then reaches the rest of the body. The capillaries are responsible for allowing the blood to receive oxygen through tiny air sacs in the lungs.
It is located at the border of the renal cortex and renal medulla. [citation needed] Arcuate veins pass around the renal pyramids at the border between the renal cortex and renal medulla in an arch shape. [1] Arcuate veins receive blood from cortical radiate veins, and in turn deliver blood into the arcuate veins. [2]
